Be it known that I, PAUL A. WEYAND, a citizen of the United States,residing at 626 South Fourteenth avenue, in the village of Maywood,county of Cook, and State of Illinois, have invented a new and usefulImprovement in Electric-Motor-Controller Regulators, of which thefollowing is a specification.

Myinvention relates to that class of dev ices designed to automaticallyregulate the move ment of the controller of electric motors.

The object of my invention is to provide an automatic regulator of cheapand simple construction that by direct and positive action retards themovementof the controllerwhile the current is being turned on, that canbe easily attached to the controller in common use, that can be timed inits movements automatically and its operative parts be perfectlylubricated.

The manner in which I accomplish my objects is described inthe-following specification, and illustrated in the accompanyingdrawings, in which Figure 1 isa side elevation showing the reg- Fig. 2is a top plan view ofthe regulator, the controller-casing not beingshown. Figs 3 is an enlarged top view of the timing device I lookinginto the box. Fig. 4is a diagrammatic view of the interior of the'baseof the regulator, showing the construction and movements of themechanism. Fig. 5 is a vertical sectional view on the line 5 5, Fig. 2,looking in the direction of the arrows. ig. 6 is an interior plan viewof the cover or top part of the regulator, showing the position, mode ofattachment of the pawl to the cover, and limit of its movement. Fig. 7is a vertical-sectional View on the line 7 7, Fig. 5, looking in thedirection of the arrows, showawl and its connection with the timin mecan- I ism. Fig. 8 is a sectional view of t e pawl on the line 8 8, Fig.7, looking in the direction of the arrows, showing the spring mechanismb which: it is held in position on, the pivot a fixed in the cover. Fig.9 is a detailed View of the pivot-stud on which the pawl is secured.Fig. 1.0 is a cross-section of the same parts on the line 10 10, showingthe recess therein. Fig. 11 is an enlarged sectional view of theair-valve forming part of the time mechanstuds C and C. On the pivot isapawl J. The pivot-hole J of the pawl is slightlyohlong, its greatestdiameter being in the direction of t 1e length of the pawl. From this 1pivot-hole J a pin-hole J extends horizone same height as the part B theseriesof the ratchet- On this l ter of the cover and passing through theI tally into the length of the pawl. Inthis hole a spring J is placedand against the spring a pin J. The pointed end of this'pin is forced bythe spring into the center of the recess 1, and thereby holds the pawlon the stud and forces the pawl back to its normal position J from thepositions J and J as shown in Fig. 6, and holds it there at all timeswhen the pawl is free from engagement with the ratchet-teeth and studs Cand C. The pressure of this spring and pin on the pawl and pivot-studholds the pivot end of the pawl close to the pivot-stud, as shown inFigs. 6 and 8. On the under side near the free end oflthe pawl is anoval post J as shown in Figs; 4,6, and 7. On the top ofthe pawl is anarm K, which extends through a slot K in the cover, in which it is freeto move.- To the upper part of this arm two cups K and K are attached,the cup K being perforated, as shown at K Fig. 5. These cups and arm arecovered by a box K, which is affixed on the cover D. This box isprovided with a lid K and an air-valve K, as

shownin detail in Fig. 11.

When the regulator is constructed as described and illustrated in thedrawings and attached to the controller, its operation and the movementof its several parts are as follows: The handle G is placed on thecontrol ler-rodG, which projects through the aper- 3 5-turn on theelectric current.

the pawl is free from contact with the ratchet which is thereby ture Ein the cover D, the shank of the handle resting in the jaw F, as shownin Figs. 1 and 2,-and in position ready to be moved to In this positionteeth and studs in the base and is held at rest in the normal position J(See Figs. l and '6.) The movement of the handle to turn on the currentrevolves the cover and pawl in the direction of the arrow M, (see Figs.2 and 4,) and as this movement con tinues the post J on the pawl strikesthe end of the first stud in the series C and slides along its outerface. This contact of the post and stud forces the free end of the pawloutward from its normal position. J to the position J and intoengagement with the first of the ratchet-teeth in the series B and stopsthe movement of the controller at the first point. The force of thecontact of the pawl and tooth is transferred through the pivot end ofthe-pawl tothe stop-block L. The oblong pivot-hole in the pawl preventsthis force'actingon the pivot-stud and allows it to force the pin- Jback on the spring J com ressed. Before the controller canbe moverf tothe next point the handle must be slightly reversed, scans to releasethe nose of the pawl from contact with the ratchet-tooth. When this isdone, the

pressure of the-spring-J forces the pin Jinto the center-of the recess 1in the pivot I. This force moves the pawl back to the normal positien J',-a'nd places the post J? between the ends of the first and'secondstuds in series C. The controller can then be moved forward again, thepost J striking theend and slldmg along the outer face of the secondstud, the

pawl being thereby forced outward into the.

pawl resumes its normal position again, and

the controller canbe then moved to the third point. These movements canbe repeated till each of the ratchet-teeth in both series have beenengagedby the pawl and all'the points have been made by the controllerand the full current thereby turned on. The reverse movement of thecontroller in the direction of the arrow N, whereby the current is cutoff, can be made at any point in the revolution of the. handle, rod, andregulatorcover. When the reverse movement begins after the pawl-post J shas passed onesor more of the studs in the series C or C, the poststrikes the reverse end of the nearest stud and slides along the insideface of the stud, thereby forcing the pawl to the inside position J, asshown in Fig. 4, and out of all possible contact with the ratchet-teethor other part of the interiorof the base. If it is desirable to retardthe movement of the pawl from the outer position J back to thenormalposition J and thereby time the movement of the controller from point topoint, it can be accomplished by providing the pawl with the arm K, cupsK and K slot K in the cover, and a box'K With the regulator soconstructed each forward movement of the controller-rod, handle, cover,and pawl compresses the cup and expels' the air from within the cupthrough the air-valve K, creates a' vacuum in the cup, and retards themovement of the pawl till that vacuum is destroyed by the flow of airthrough the airvalve. This flow of air can be regulated by theadjustment of the air-valve. The cup K when compressed by the reversemovement simply assists the action of the spring -J 3 and pin J inforcing thepawhfrom the position J back to the position J The interiorof the base may be filled with a suitable lubricant to reducenthefriction of the moving parts, the cylindrical part B? and wall 13 of thebase and the cover D and the wall E being sufficient to retain thelubricant within the base.
